# 4DReplay

> 4DReplay is a media technology company that builds multi-camera, time-slice ("bullet-time") video capture and replay systems for live sports, entertainment and events. Arrays of roughly 50 to 120 synchronized cameras — locked to within 1/10,000 of a second — are processed in real time to produce any-angle replay highlights within seconds of a play and deliver them to broadcast, mobile and OTT audiences. Founded in 2012 by Hongsu Jung; headquartered in San Mateo, California with offices in Seoul and Tokyo.

As of 2026-08-02, 4DReplay publishes **no public developer API**: no OpenAPI, Swagger,
GraphQL, AsyncAPI, MCP server, A2A agent card, SDK, CLI, Postman collection, developer
portal, sandbox, status page, changelog, or `/.well-known/` discovery document was found

`mcp.4dist.com` all serve the same 4Dist landing page and are not an API host, a status
page, or an MCP server.
